Precatalyst activation paper published in Organometallics

4/16/2018

0 Comments

 
A paper authored by Kerry Barnett, James Howard, Renee Stullich, Adam Shipley, and Colin Treager entitled, "Air-Stable [(R3P)PdCl2]2 Complexes of Neopentylphosphines as Cross- Coupling Precatalysts: Catalytic Application and Mechanism of Catalyst Activation and Deactivation," was published in Organometallics.  This paper describes the use of [(R3P)PdCl2]2 complexes as catalysts in the Suzuki coupling.  A study of the mechanism of conversion of the Pd(II) precatalyst to the Pd(0) active species showed that palladacycle formation was a competitive pathway in acetonitrile.  Switching the solvent to toluene eliminated formation of the palladacycle byproduct.  This solvent switch allowed a 50-fold decrease in catalyst loading.
